Identify Flush valve ....help

[Lennyp77]

Hello there I'm looking for some help with this flush valve, it's fitted into a low level cistern and i would like to know if anyone has seen one before, I can't put a new flush valve in because its tiled in grrrr!! Any help would be greatly appreciated. its got no writing on it so I'm stuck really.

Easiest way is probably to identify the button first then go to relevant flush valve section;
